R-Gate single qubit operation completes redistribution of state for |0> and |1> inputs for the 1st qubit.
In the circuit | zero, hihil, yeong > two equally likely input state vectors |000> and |011> are spread to four equally likely input state vectors |000>,|100>,|011> and |111>.
In the circuit | four, quattuor, sa > the inputs |110>,|101> have also been evenly split to |000>,|100>,|011> and |111>.
